Description

Terminal resident network selection method, device and terminal

Technical field

The present invention relates to the field of communications, and in particular, to a method, an apparatus, and a terminal for selecting a terminal resident network.

Background technique

With the maturity of 4G Long Term Evolution (LTE) technology, more and more operators are beginning to set up 4G LTE networks. However, the network coverage of LTE is not perfect, and there are many areas where LTE has weak coverage or no coverage.

The LTE network is a packet switching (PS) network. It only supports data services and does not support traditional circuit switching (CS) voice services. If you want to use voice calls under the LTE network, do you want to use VoLTE, or fall back to the traditional 3G and 2G networks, such as Code Division Multiple Access (CDMA), Global Mobile Communications ( Global system for Mobile Communication (referred to as GSM) or Wideband Code Division Multiple Access (WCDMA).

Because LTE has a weak coverage area and does not support CS voice services, the terminal is required to support not only the LTE system but also other standards, such as CDMA and Gateway (GW). This allows other formats to be used without LTE network coverage. However, the prior art only stipulates that the terminal searches for other networks when the LTE network cannot be searched. However, there is no good solution to the problem of LTE network speed reduction and missing signaling when LTE is weakly covered.

For the related technology, when the LTE is weakly covered, the terminal cannot search for the network access problem of other standards, and an effective solution has not been proposed.

Signal strength of other standard networks other than the first standard network, wherein the first standard network The signal strength is greater than 0; and a second mode network having a signal strength greater than a second threshold is selected from the other system networks to camp.

The first standard network is a long term evolution LTE network, and the second standard network is a 2G network or a 3G network.

The method also includes the terminal continuing to reside in the first mode network when a signal strength of the first mode network is greater than the first threshold.
